A Plastic-neuro Effort: Vascularized Soft-tissue Coverage for Hostile Wound Bed with Multiple Ventricular Shunt...

Cerebral ventricular shunt placements are the most common neurosurgical procedure performed today, which play a life-long role in the care of patients with hydrocephalus. Complication rates requiring shunt replacement are as high as 25%, and the potential need for multiple revisions throughout a patient's life may result in the formation of scar tissue and compromised wound healing. Without addition of vascularized tissue, patients with scalp scarring and impaired wound healing then enter a cycle of impaired skin closure followed by shunt infection, failure, and revision with little promise of long-term operative or therapeutic success. This plastics-neuro collaboration is the first known report of a free vastus lateralis muscle flap for coverage of a cerebral ventricular shunt, in a patient with congenital hydrocephalus and 17 previous ventricular shunts revisions due to infections and soft tissue exposure from scarring and a hostile wound bed. In the setting of extensive scarring, the free vascularized muscle flap provides soft tissue and vascular supply capable of promoting wound healing, maintaining scalp integrity, and reducing the incidence of shunt infection and the subsequent need for future revision, as supported by the complication-free status of the same patient now 16 months since the date of operation.
